"At 0935 [CST] on 12/21/2016, while performing the High Pressure Coolant Injection (HPCI) Comprehensive Pump and Valve Tests for post-maintenance testing following scheduled maintenance, the HPCI turbine did not start as expected due to the HPCI turbine stop valve failing to open. This issue is being reported under 10CFR50.72(b)(3)(v)(D) as a condition that could have prevented the fulfillment of a safety function at the time of discovery. Investigation into the failure of the HPCI system to start is in progress. The plant remains at 100% power with no challenges to the health and safety of the public.
"The NRC Resident Inspector has been notified."
The plant is in a 14-day action statement under LCO 3.5.1, 'ECCS - Operating' due to the HPCI turbine stop valve failure.
The licensee notified the Minnesota State Duty Officer.

"On December 21, 2016, the NRC Operations Center was notified of Event Number 52454 that described a failure of the High Pressure Coolant Injection (HPCI) turbine stop valve to open during post maintenance testing prior to being declared operable. The condition was reported in accordance with 10 CFR 50.72 (b)(3)(v)(D) as a condition that could have prevented the fulfillment of a safety function at the time of discovery. At the time, it was not readily apparent that the failure was due to the maintenance activities. Subsequent return-to-service testing showed the oil system vent and fill had been inadequate following the maintenance. This event occurred as a result of the maintenance process and would not have occurred during normal operation of the system.
''NUREG-1022, Revision 3 states, 'reports are not required when systems are declared inoperable as part of a planned evolution for maintenance or surveillance testing when done in accordance with an approved procedure and the plant's TS (unless a condition is discovered that would have resulted in the system being declared inoperable).'
"There was no discovered condition that would have resulted in the safety function of the system being declared inoperable under normal, non-maintenance conditions.
"Based on the above additional information, Monticello Nuclear Generating Plant is retracting this report. The plant was in a planned evolution and did not discover a condition that could have prevented performing a safety function.
"The licensee has notified the NRC Resident Inspector."

The following information was received via facsimile:
"Licensee notified the Department on 11/23/16, of the theft of an RMD LPA-1 Lead-Paint Analyzer containing 12 milliCuries of Cobalt-57 (Device S/N 3447R). The theft occurred at approximately 1030 EST on 11/23/2016 at a temporary jobsite located at 40-01 Vernon Boulevard, Queens, New York 11101.
"According to the licensee, the authorized user realized the device was missing shortly after departing the jobsite. He recalled putting the protective case containing the XRF [X-Ray Fluorescence Lead Paint Spectrum Analyzer] on the ground next to his vehicle to access his vehicle keys. Soon after, he was distracted by a pedestrian asking for directions and stepped into his vehicle to travel to the next jobsite without the device. He immediately returned to the previous site to search for the device. He was unsuccessful in his search.
"After filing a report at the local police department, the authorized user returned to the jobsite. He was informed by the maintenance department that there was video surveillance at that location and was provided a copy of the tape. This video showed two men walking away with the XRF protective case from the location where the authorized user's vehicle was originally parked. The licensee indicated that fliers were put up in the neighborhood where the device was originally stolen with a reward for the safe return of the XRF.
"On December 8, 2016, the Radiation Safety Officer (RSO) notified the Department [New York State Department of Health] that someone had contacted their office claiming to have the stolen XRF in their possession. The RSO verified it was the correct device by the S/N and arranged to retrieve the device the next day. Two of the Licensee's authorized users met the individual at the previously agreed upon location, paid the negotiated reward, and retrieved the device. The XRF and XRF accessories appeared to be in perfect condition."

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

| Event Text FAILURE OF THE REGULATING BLADE TO MOVE
"On 1/17/17 at 2130 CST, the MURR [University of Missouri Research Reactor] was shut down due to the failure of the regulating blade to move. This email is a required notification per MURR TS 6.6.c.(1) to report to the NRC Operations Center that an Abnormal Occurrence as defined by MURR TS 1.1 happened. Specifically, MURR was not in compliance with all Limiting Conditions for Operations (LCOs). MURR was not in compliance with the LCO TS 3.2.a. which states, 'All control blades, including the regulating blade, shall be operable during reactor operation.' The regulating blade was repaired, and the required compliance procedure was conducted on the regulating blade prior to the reactor being started up on 1/18/17. Currently, MURR is again at 10 MW. A detailed event report will follow within 14 days as required by MURR TS 6.6.c.(3)."
The reactor was at 10 MW power when this event occurred. The cause of this event is under investigation.

"This report is being made pursuant to 10 CFR 50.72(b)(3)(v)(C), event or condition that could have prevented fulfillment of a safety function needed to control the release of radioactive material and 10 CFR 50.72(b)(3)(v)(D), event or condition that could have prevented fulfillment of a safety function needed to mitigate the consequences of an accident. An employee entered a secondary containment interlock [airlock] and identified that both doors of the interlock opened simultaneously when the door on the reactor building side was opened. The employee immediately secured both doors in the interlock and notified the Main Control Room Supervisor. Both doors in the interlock were open for approximately five seconds. With both doors open, TS SR 3.6.4.1.2 was not met. This rendered secondary containment inoperable per TS 3.6.4.1. Reactor Building differential pressure, as observed in the Main Control Room has remained less than -0.25 in. H2O at all times. Initial investigation determined that the interlock for the doors was malfunctioning. Administrative controls have been put in place to ensure the doors remain closed pending repairs to the interlock."
The licensee notified the NRC Resident Inspector.
